Step S20, acquiring target video playing parameters of the video to be processed according to the playing scene;
in this embodiment, the target video playing parameter may be understood as a picture display attribute when playing a video, and the target video playing parameter includes, but is not limited to, at least one of brightness, contrast, color saturation, sharpness, color temperature, and sharpness. After the playing scene of the video to be processed is obtained, there are two ways to obtain the target video playing parameter according to the playing scene: one method is that operation and maintenance personnel or users preset different video playing parameters for different playing scenes, namely preset video playing parameters, after the playing scene of the video to be processed is obtained, the preset video playing parameters corresponding to the playing scene can be obtained, and then the video to be processed is played according to the preset video playing parameters, so that the video playing parameters can be automatically adjusted according to the playing scene of the video, and the matching degree of the video playing parameters and the characteristics of the video is improved; the other method is to record adjustment data of the video playing parameters of each playing scene, namely historical video playing parameters, of the user, wherein the historical video playing parameters corresponding to each playing scene can reflect the video playing parameters which are adopted by the user when the video corresponding to the playing scene is played in the past, for example, the historical video playing parameters corresponding to the playing scene a can reflect the video playing parameters which are adopted by the user when the video corresponding to the playing scene a is played in the past, and the historical video playing parameters corresponding to the playing scene B can reflect the video playing parameters which are adopted by the user when the video corresponding to the playing scene B is played in the past; and each playing scene is stored in association with the corresponding historical video playing parameter. After the playing scene of the video to be processed is obtained, the historical video playing parameters corresponding to the playing scene can be obtained, and then the target video playing parameters are determined according to the historical video playing parameters. The two modes can be implemented individually or in combination, and the embodiment is not particularly limited.
And step S30, playing the video to be processed according to the target video playing parameters.
In this embodiment, after the target video playing parameter is obtained, the television can play the video to be processed by using the target video playing parameter.
The embodiment obtains the playing scene of the video to be processed; acquiring a target video playing parameter of the video to be processed according to the playing scene; and playing the video to be processed according to the target video playing parameters. Corresponding target video playing parameters are obtained according to the characteristics of the video, the video is played by adopting the target video playing parameters, the video playing effect can be more fit with the characteristics of the video, the video playing effect is further improved, and the watching experience of a user is improved.
Further, a second embodiment of the video playing method of the present invention is provided, wherein the step S20 includes:
step S201, acquiring video playing parameters corresponding to the video to be processed according to the playing scene;
step S202, determining target video playing parameters according to the video playing parameters corresponding to the video to be processed.
In this embodiment, to determine the target video playing parameter of the video to be processed, first, a video playing parameter corresponding to the video to be processed is obtained, where the video playing parameter corresponding to the video to be processed includes a historical video playing parameter and/or a preset video playing parameter.
Specifically, if the video playing parameter corresponding to the video to be processed only includes a preset video playing parameter, after the playing scene of the video to be processed is obtained, the preset video playing parameter corresponding to the playing scene is obtained, and the preset video playing parameter is used as a target video playing parameter; if the video playing parameters corresponding to the video to be processed only comprise historical video playing parameters, judging whether the playing scene has the historical video playing parameters, if so, acquiring the historical video playing parameters of the playing scene, determining target video playing parameters according to the historical video playing parameters of the playing scene, and if not, taking default playing parameters set by operation and maintenance personnel or a user as the target video playing parameters;
if the video playing parameters corresponding to the video to be processed comprise historical video playing parameters and preset video playing parameters, firstly judging whether the playing scene has the historical video playing parameters or not, if so, acquiring the historical video playing parameters of the playing scene, determining target video playing parameters according to the historical video playing parameters of the playing scene, if not, acquiring the preset video playing parameters corresponding to the playing scene, and taking the preset video playing parameters as the target video playing parameters; further, if there is a history video playing parameter in the playing scene, it is also necessary to determine whether the history video playing parameter of the playing scene is the same as a preset video playing parameter corresponding to the playing scene, and if not, the following steps are executed: acquiring historical video playing parameters of the playing scene, and determining target video playing parameters according to the historical video playing parameters of the playing scene; if the video playing parameters are the same, taking the historical video playing parameters of the playing scene or the preset video playing parameters corresponding to the playing scene as the target video playing parameters.
In the above three specific situations of the video playing parameters corresponding to the video to be processed, the operation and maintenance personnel or the user can select the parameters according to the needs, and this embodiment is not limited specifically.
It can be understood that, in a one-time playing process of a playing scene, the same user may adjust the video playing parameter for multiple times to find the most satisfactory playing parameter, and play the video with the parameter, so that the time length of playing the video with the parameter is much longer than the middle adjustment value, and therefore, the historical video playing parameter refers to the video playing parameter corresponding to the time period in which the playing time length after each adjustment is the longest in multiple adjustments of the user in the playing scene within the preset time period; the historical video playing parameter may also be a video playing parameter obtained by the last adjustment performed by the user in the one-time playing process of one playing scene, and the historical video playing parameter is not specifically limited in this embodiment.
Further, the video playing parameters corresponding to the video to be processed include historical video playing parameters and preset video playing parameters, and the step S201 includes:
step A21, judging whether the playing scene has historical video playing parameters;
step A22, if yes, obtaining historical video playing parameters of the playing scene;
correspondingly, the step S202 includes:
step A23, screening the historical video playing parameters according to the distribution condition of the historical video playing parameters of the playing scene to obtain target video playing parameters.
In this embodiment, the video playing parameters corresponding to the video to be processed include historical video playing parameters and preset video playing parameters. After a playing scene of a video to be processed is acquired, whether historical video playing parameters exist in the playing scene or not is judged, if yes, the fact that the user plays the video of the playing scene in the past is indicated, and in order to enable the video playing effect to be more fit with the watching habit of the user, the historical video playing parameters reflect the watching habit of the user, therefore, when the historical video playing parameters exist in the playing scene, the historical video playing parameters which are stored in association with the playing scene are acquired, the target video playing parameters are determined according to the historical video playing parameters of the playing scene, and specifically, the historical video playing parameters are screened according to the distribution situation of the historical video playing parameters of the playing scene, and the target video playing parameters are obtained.
If not, acquiring a preset video playing parameter corresponding to the playing scene, and taking the preset video playing parameter corresponding to the playing scene as a video playing parameter corresponding to the video to be processed.
Further, before step a21, the method further includes: recording video playing parameters of each playing scene during historical playing of a user, namely obtaining historical video playing parameters, and managing and storing each playing scene and the historical video playing parameters thereof.
Further, since the historical video playing parameters may include video playing parameters that have been adjusted by the user, or may include preset video playing parameters corresponding to the playing scene, if it is not considered that whether the historical video playing parameters are the same as the preset video playing parameters, the historical video playing parameters are directly obtained and screened, so that the obtaining efficiency of the target video playing parameters is reduced, and in order to avoid this, the present embodiment determines whether to execute step a22 according to whether the historical video playing parameters are the same as the preset video playing parameters. Specifically, if the playing scene has a historical video playing parameter, determining whether the historical video playing parameter of the playing scene is the same as a preset video playing parameter corresponding to the playing scene, and if not, indicating that the playing effect of the preset video playing parameter or a default playing parameter of the playing scene is unsatisfactory in the historical playing process of the user, executing the following steps: acquiring historical video playing parameters of the playing scene, and determining target video playing parameters according to the historical video playing parameters of the playing scene; if the difference is the same, it indicates that the playing effect of the preset video playing parameter of the playing scene by the user is satisfactory in the history playing process, and therefore, the adjustment is not performed on the basis of the preset video playing parameter of the playing scene, and therefore, in the playing of this time, the history video playing parameter of the playing scene or the preset video playing parameter corresponding to the playing scene is still used as the target video playing parameter.
It can be understood that, in a one-time playing process of a playing scene, the same user may adjust the video playing parameter for multiple times to find the most satisfactory playing parameter, and play the video with the parameter, so that the time length of playing the video with the parameter is much longer than the middle adjustment value, and therefore, the historical video playing parameter refers to the video playing parameter corresponding to the time period in which the playing time length after each adjustment is the longest in multiple adjustments of the user in the playing scene within the preset time period; the historical video playing parameters can also be video playing parameters obtained by the last adjustment of a user in the one-time playing process of one playing scene; the historical video playing parameter may also be a preset video playing parameter corresponding to the current playing scene, and the embodiment does not specifically limit the historical video playing parameter.
Further, after the step a21, the method further includes:
step A24, if not, acquiring preset video playing parameters corresponding to the playing scene;
correspondingly, the step S202 includes:
step A25, using the preset video playing parameter corresponding to the playing scene as the target video playing parameter.
In this embodiment, if there is no history video playing parameter in the playing scene, it is stated that the user has not played the video of the playing scene in the past, and therefore the target video playing parameter cannot be determined according to the habit of the user playing the video of the playing scene in the past, the preset video playing parameter corresponding to the playing scene is obtained, the preset video playing parameter is used as the target video playing parameter, and the target video playing parameter is used to play the video, so that the video playing effect can be more similar to the characteristic of the video itself, and further, the video playing effect is improved, and the viewing experience of the user is improved.
Further, the step S201 includes:
step S2011, acquiring the video content type of the video to be processed in the playing scene;
step S2012, a video playing parameter corresponding to the video to be processed is obtained according to the video content type.
In this embodiment, operation and maintenance personnel or users can set different video content types for different playing scenes according to needs, the video content types are more detailed classification of videos according to the video playing contents, for example, the video content types in the movie playing scene can include swordsmen, comedy, horror, disaster, suspense, action, and the like, and the video content types in the sports playing scene can include football events, sports events, and the like, In basketball events, baseball events, swimming events, shooting events, and the like, if different video content types in the same playing scene are set as uniform video playing parameters, the degree of engagement between the video playing parameters and the video playing contents is still not high enough, and in order to further improve the degree of engagement between the video playing parameters and the video playing contents, in this embodiment, after the playing scene of the video to be processed is obtained, the video to be processed also needs to be subjected to content analysis to obtain the video content type of the video to be processed in the playing scene.
After the video content type of the video to be processed in the playing scene is determined, video playing parameters corresponding to the video to be processed are obtained according to the video content type, where the video playing parameters corresponding to the video to be processed include historical video playing parameters and/or preset video playing parameters.
Further, the step a23 includes:
step A231, obtaining the distribution quantity of the historical video playing parameters of the playing scene in each preset numerical value partition of each video playing parameter;
step A232, determining a target partition with the maximum distribution quantity of each preset numerical value partition of each video playing parameter according to the distribution quantity of the historical video playing parameters of the playing scene in each preset numerical value partition of each video playing parameter;
step A233, determining the target video playing parameters according to the historical video playing parameters in the target partition of each video playing parameter.
In this embodiment, the operation and maintenance staff preset different value partitions, that is, preset value partitions, for different video playing parameters, and after the user adjusts the video playing parameters each time, the television will count the distribution number of the historical video playing parameters of each playing scene in each preset value partition of each video playing parameter again. Therefore, after determining that the historical video playing parameters exist in the playing scene of the video to be processed, the distribution condition of the historical video playing parameters of the playing scene in each preset value partition of each video playing parameter can be obtained. And determining the partition with the largest number of historical video playing parameters, namely the target partition, in the plurality of preset numerical value partitions of each video playing parameter according to the distribution condition, wherein each video playing parameter has a corresponding target partition.
After the target partition of each video playing parameter is determined, determining the target video playing parameter according to the value of the historical video playing parameter in the target partition of each video playing parameter, wherein one mode comprises the following two modes, namely calculating the average value of the values of the historical video playing parameter in the target partition of each video playing parameter, and taking the average value obtained by calculating each video playing parameter as the target video playing parameter; and another way is to use any one of the values of the historical video playing parameters in the target partition of each video playing parameter as the value of the corresponding video playing parameter, and the two ways are alternatively implemented, which is not limited in this embodiment.

Further, a third embodiment of the video playing method according to the present invention is provided, where after the step S30, the method further includes:
step S41, monitoring the attribute of the ambient light;
and step S42, when the attribute of the ambient light changes, adjusting the video playing parameters of the video to be processed according to the change condition of the attribute of the ambient light.
When the user watches video, the ambient light may change, for example, when the ambient light has brightness and darkness, if the brightness of the tv is not changed, the brightness of the display screen may have a large brightness and darkness contrast with the ambient light, which may cause damage to the user's eyesight, or when the color temperature of the ambient light changes from cold light to warm light, if the color temperature of the tv is not changed, the color temperature of the display screen may have a large color temperature contrast with the ambient light, which may cause damage to the user's eyesight. To avoid this, in the process of playing the video to be processed according to the video playing parameters acquired in step S20, the ambient light sensor detects the attribute of the ambient light at a certain frequency or in real time, and when the attribute of the ambient light changes, the video playing parameters of the video to be processed are adjusted according to the change of the attribute of the ambient light. The attributes of the ambient light include, but are not limited to, brightness, light level, light quality, light type, light ratio, light color, etc.
This embodiment is through monitoring the ambient light attribute, when the ambient light attribute changes, corresponds the video broadcast parameter of adjustment video to reduce the light of display screen and the attribute difference of ambient light, minimize the harm to user's eyesight, promote user's video and watch experience.
Further, taking the example that the attribute of the ambient light includes the ambient light intensity as an example, the step S42 further includes:
step S423, when the ambient light brightness changes, obtaining a curve conversion value corresponding to the changed ambient light brightness;
the embodiment is a process for specifically adjusting the playing brightness of a video to be processed. Firstly, calculating to obtain a middle brightness value according to the ambient light brightness, the minimum range of the ambient light sensor and the maximum range of the ambient light sensor, wherein the specific calculation formula is as follows:
A＝light_min+(100-light_min)*(adc_val-adc_min)/(adc_max-adc_min)；
wherein A is an intermediate luminance value;
adc _ min is the minimum range of the ambient light sensor;
adc _ max is the maximum range of the ambient light sensor;
adc _ val is the measured value of the ambient light sensor, i.e. the ambient light brightness after change;
light_min＝4*adc_min。
after the intermediate brightness value is obtained, a corresponding curve conversion value can be obtained through calculation by a conversion formula of the intermediate brightness value and the curve conversion value preset by operation and maintenance personnel; the corresponding relationship between the middle brightness value and the curve conversion value may also be preset by the operation and maintenance staff to obtain the corresponding curve conversion value, which is not limited in this embodiment.
Step S424, obtaining a corresponding backlight value according to the curve conversion value corresponding to the changed ambient light brightness;
in this embodiment, after obtaining the curve conversion value corresponding to the changed ambient light brightness, the corresponding backlight value is obtained according to the magnitude of the curve conversion value.
To aid understanding, an example is now listed: a is a curve conversion value corresponding to the changed ambient light brightness, ba is a backlight value corresponding to a, a is a curve conversion value corresponding to a backlight value of 0, B is a curve conversion value corresponding to a backlight value of 25, C is a curve conversion value corresponding to a backlight value of 50, D is a curve conversion value corresponding to a backlight value of 75, and E is a curve conversion value corresponding to a backlight value of 100.
If a is less than or equal to A, ba is 0;
if a < a ≦ B, ba ═ 25 ═ a (a-a) × 100/(B-a)/100;
if B < a ≦ C, ba ═ 25+25 ≦ (a-B) × 100/(C-B)/100;
if C < a ≦ D, ba ═ 50+25 ≦ (a-C) × 100/(D-C)/100;
if D < a < E, ba ═ 75+25 ═ a-D ═ 100/(E-D)/100;
if a is more than or equal to E, ba is 100.
The division of the backlight values 0, 25, 50, 75, and 100 is only exemplary, and the operation and maintenance staff may adjust the specific backlight values according to the needs, and correspondingly, the curve conversion values corresponding to the backlight values are also changed, and this embodiment is not limited in particular.
Step S425 is to adjust the playing brightness of the video to be processed according to the backlight value.
After the backlight value needing to be adjusted is obtained, the backlight of the television is adjusted to the corresponding backlight value, so that the playing brightness of the video to be processed is in the brightness which enables a user to have better watching experience.
Further, before step S423, the method further includes:
acquiring a difference value between the brightness of the ambient light and the playing brightness of the video to be processed;
if the difference between the ambient light brightness and the playing brightness of the video to be processed is greater than or equal to the preset difference threshold, step S423 is executed.
In this embodiment, the preset difference threshold is set by an operation and maintenance person according to a brightness difference between the ambient light brightness and the video playing brightness, where human eyes can feel obvious discomfort, and if the difference between the ambient light brightness and the playing brightness of the video to be processed is smaller than the preset difference threshold, a user watching the video does not feel obvious discomfort, so as to avoid that the watching experience of the user is affected by frequently adjusting the brightness of a television when the ambient light brightness frequently changes, and therefore, the playing brightness of the video to be processed is not adjusted at this time; however, if the difference between the ambient light brightness and the playing brightness of the video to be processed is greater than or equal to the preset difference threshold, a user watching the video may feel uncomfortable, and if the user watches the video for a long time, the user may have an adverse effect on the eyesight.
By monitoring the brightness of the environment, the embodiment adjusts the playing brightness of the video to be processed when the brightness of the environment changes. The uncomfortable feeling of the user watching the video when the ambient light changes can be avoided, and the watching experience of the user is further improved.
